Dialog box doesn't resize properly

This image demonstrates the issue pretty clearly:

Salvage droids on Taris have the same problem, but dialogs with all other NPCs in the area resize well. So there is code to calculate text size and resize the box, but it is inconsistent.

The problem is in BarkBubble::setBarkText. This function attempts to measure text, calculates the number of lines it is going to take, and resizes extent with some padding. Then it calls Control::setTextMessage, which uses another routine to break text into lines in Control::updateTextLines. These two routines are inconsistent: for the droids on Taris, BarkBubble calculates 2 lines, and updateTextLines breaks text into 3 lines.

I think we can remove calculation of lineCount from BarkBubble:

1. Use Control::setTextMessage first, let it break text into lines.
2. Take the number of lines from the control.
3. Calculate total height for setExtentHeight as before.

I think it is a "good first issue" for Taris milestone.
